给出了一种利用非对称高频电场在稠密空气-气体介质中进行离子分离的新方法的一般原理。该方法利用各个横向离子迁移率系数对电场的依赖关系不同，实现了离子分离。的漂移光谱的离子从一个同源系列的叔胺，以及质谱鉴定的各种离子的迁移率谱中的单独的峰的结果。连续记录和识别大气中微量胺的可能性。
The general principles of a new method of ion separation in dense air-gas media using an asymmetric high-frequency electric field are given. With this method ion separation is realized due to the different dependences of the individual transverse ion mobility coefficients on the electric field. The drift-spectra of the ions from a homological series of tertiary amines are presented as well as the results of mass spectrometric identification of the various ions representing the separate peaks in the mobility spectra. The possibility of continuous recording and identification of trace amounts of amines in atmospheric air is shown.
